Purpose - Japan's decision to release nuclear wastewater into the Pacific Ocean in 2023 has sparked strong opposition at home and abroad. In this study, Graph Model for Conflict Resolution (GMCR) method is adopted to analyze the conflict problem, and reasonable equilibrium solutions are given to...

Pharmaceutical residues are released in the aquatic environment due to incomplete removal from wastewater. With the presence of multiple chemicals in sewage waters, contaminants may adversely affect the effectiveness of a wastewater treatment plant (WWTP). In certain cases discharged metabolites...

Abstract: The contamination of soil and water with heavy metals, such as cadmium and lead, is a serious problem. Previous remediation techniques are not effective when these two toxic elements are immobilized. Microbial induced carbonate precipitation has been proven to effectively remove heavy...

With the increase in shipping density, the risk of wastewater generated by ships in coastal areas has raised much attention. The present study proposes a model to estimate the spatiotemporal distribution of wastewater including greywater and sewage generated by ships in coastal areas. The model...

The effect of anaerobic sludge digestion on the isolation of DNA and clean-up efficiency of obtained DNA isolates was studied. Sludge samples were taken from a mesophlic full-scale, and batch digesters operated under mesophilic and thermophilic conditions. Declines over 90% in the extraction...

Microwave-assisted Fenton process over a high microwave-responsive catalyst (Fe3O4-BiOCl) was developed to environment-friendly treat toluene nitrification wastewater. The morphology, composition and magnetic recovery of the prepared catalyst were analyzed using various analytical instruments....

Wastewater-based epidemiology (WBE) approach for COVID-19 surveillance is largely based on the assumption of SARS-CoV-2 RNA shedding into sewers by patients. Recent studies found that SARS-CoV-2 RNA concentration in wastewater (CRNA) could not be accounted by the fecal shedding alone. This study...

Incorporating uranium into magnetite crystal from wastewater to limit its mobility have been proposed to the long-term remediation of radioactive contamination. Unfortunately, this process is accompanied by reduction or surface adsorption, which significantly reduces the incorporation capacity...

Cu(II)-EDTA is a highly stable typical metal-organic complex in a wide pH range (3.0-12.0) and difficult to deeply purify Cu(II) by conventional precipitation methods. In this study, Fe(III) replacement/diethyldithiocarbamate (DDTC) precipitation combined process was proposed as a promising...

An increased energy recovery efficiency can be obtained from biomass waste due to coupling hydrothermal carbonation (HTC) with anaerobic digestion (AD). This study focused on optimizing the total energy yield (TEY) from sewage sludge (SS) and pinewood sawdust (PS) in co-HTC-AD coupling process,...

Solar-driven interfacial evaporation is considered a promising solution to water pollution and water shortages, potentially reducing heat loss and improving energy conversion efficiency. However, the current photothermal films used for solar-driven interfacial water evaporation have some issues...

Wastewater and pollution management issues are usual negative externalities in the pursuit of economic development. This is true in the Philippines where industrial and domestic refuse often end up in tributaries and major waterways, sometimes even contaminating groundwater due to improper...

This Briefing Paper presents one of six analyses of cross-sectoral coordination challenges that were conducted as part of the STEER research project and on which separate Briefing Papers are available. The extraction of minerals and metals comes with a large water footprint, both in terms of...

Diese Veröffentlichung stellt eine von sechs Analysen sektorenübergreifender Herausforderungen für Wasser-Governance dar, die als Teil des STEER-Forschungsprojekts durchgeführt wurden und deren Resultate in separaten Analysen und Stellungnahmen vorliegen. Der Abbau von Mineralien und...

D0 bleaching wastewater from E. globulus Kraft pulping industry was treated by Fenton and photo-Fenton processes. The aim was to optimize the operational conditions for adsorbable organic halides (AOX) removal, namely oxidant concentration, [H2O2], catalyst concentration, [Fe2＋], and treatment...

The decline in annual rainfall, coupled with the growing demand for water in agricultural fields, triggered a new crisis in today's world. Thus, the focus is on finding solutions to new water resources. Taking a look at the normal daily life, most of the households' effluents can be ranked into...

A set of case studies was prepared as part of the World Bank's Water Global Practice initiative "Wastewater: from waste to resource" to document existing experiences in the water sector on the topic. The case studies highlight innovative financing and contractual arrangements, innovative...

SEDAPAR S.A. (Servicio de Aqua Potable y Alcantarillado de Arequipa) is one of the public service enterprises in Peru. It is a limited liability company owned by 8 provincial municipalities and 26 district municipalities in Arequipa Department. It provides water and sanitation services to the...

Privatization of a public good (the management of sewage treatment centers in Dakar, Senegal) leads to an increase in the productivity of downstream sewage dumping companies and a decrease in downstream prices of the services they provide to households. We use the universe of legal dumps of...

The water-food nexus in the Middle East and Northern African (MENA) region is characterized by resource depletion, import dependence and environmental degradation. This contribution proposes that consumption awareness and resource circularity can be seen as a pathway to alleviate environmental...

Currently, the constantly growing problem in the municipal economy is the management of sewage sludge. According to the law, it is the local government that is responsible for the utilization of sewage sludge and is obliged to select optimal technologies, obtain funds and convince the community...

Properly managed sanitation systems and improved wastewater treatment are important for safeguarding environment and enhancing sustainable livelihoods in vast areas of South and Southeast Asian countries. Recovering nutrients and energy from organic waste and wastewater is an effective option...

Public-private partnership (PPP) contracts are frequently used in the provision of public services. One of the key points to consider in these contracts (and from which much of its convenience derives) is the allocation of risks to the party that has the best capacity to avoid them or, if they...

The objective of this paper is a theoretical and empirical analysis and evaluation of the role, importance and opportunities of the water-sewage-sludge industry in the implementation of the circular economy. To realize this objective, a review of both the literature and the EU strategic...

Wastewater use in agriculture is a growing practice worldwide. Drivers include increasing water stress, in part due to climate change; increasing urbanization and growing wastewater flows; and more urban households engaged in agricultural activities. The problem with this trend is that in...
